A5 Claims.

This invention relates to improvements in clothes wringers and particularly has in view the development of a low, compact form of Wringer which is simple in construction and operation,

5 easy to assemble, and readily and quickly thrown into and out of operation.

' Al feature of the invention is the provision of a.

single lever which serves to simultaneously apply pressure between the rollers and connect o them with the driving mechanism. The same lever is adapted to be readily operated in either direction to effect a quick release of the pressure and a disconnection of the rollers from the driving mechanism. In carrying out this feature of 5 the invention suitable cams are mounted directly upon a shaft which supports one of the rollers and these cams are adapted to connect this roller with certain tensioning devices for creating a desirable pressure between the pair of rollers.

In the connection of the rollers with the tensioning devices an increase in the tension of the latter is preferably brought about. v.

Other features and advantages of the invention will appear from a detailed description which will now be given of a suitable, illustrative form of the same in conjunction with the accompanying drawings in which:

Fig. 1 is a vertical longitudinal section through the illustrative form of wringer.

Fig. 2 is a vertical, transverse section along the `line 2-2 of Figure 1.

Fig. 3 is a vertical, transverse section along the broken line 3-3 of Figure 1.

Fig. 4 is a vertical, transverse section along the i5 line 4 4 of Figure 1. A

Fig. 5 is a side elevational view of the wringer with a portion in section and the cover removed, showing the rollers in ineffective positions, and

A Fig. 6 is a vertical, transverse section along :0 the line 6-6 of Figure 5.

' Referring now to the drawings there,V may be suitably provided a main frame member 10 having vertically disposed end portions 11 and 12. A gear housing 13 may be formed as an integral '=5 part of the frame or as a separate member secured to the frame. In a, trough formed in the frame 10 there is mounted a roller 14 which may comprise, for example, an outer cylinder of rubber or similar softlelastic material carried by a 50 metal sleeve 15. At the ends of this sleeve there may suitablybe provided bushings 16, formed of brass or similar good bearing material, within which may be mounted a solid shaft 17. This shaft will serve as a stationary support about 55 which the roller will be rotated. At its right end (Figure 1) the shaft may be formed with a flattened portion 18 which fits into a guide groove 19 provided in the frame and rests upon a shoulder 20 of the frame. A similar flattened portion 5.0 21 at the opposite end of the shaft nts in a guide groove 22 in the frame and rests upon a plunger 23 which fits in a socket 24 in the frame and is urged upwardly by a spring 25. Normally this end of .the shaft will be elevated into the position shown in Figure 5 but when pressure is applied from above, as will be explained, it will be `de pressed until it engages a solid portion of the frame, as shown in Figure 1.

Above the roller 14 there is mounted a second substantially similar roller 26 consisting, for example, of rubber surrounding a sleeve 27 having brass bushings 28 or the like within its ends adapted `to lreceive a solid shaft 29. The roller is in thisY way mounted for free rotation upon the shaft. At each end the shaft is held between guide surfaces formedgby the walls of forked projections 30 of bracket members 31. The bottoms of these brackets are formed with lat-eral projections 32 having threaded openings adapted to receive the upper ends of bolts 33. 'Ihese bolts pass freely through a shelf portion 34 provided at each end of the frame. Springs 35 surrounding the' bolts and compressed' between the under surfaces of the shelves 34 and washers 36 at the heads of the bolts normally urgeI the brackets 31 downwardly until their projections 32 engage the shelves 34. By simply turning the bolts the normal tension on the springs may be varied to suit the particular requirements. At

each end of the shaft 29 there is secured a semicircular cam element 37 having a raceway in its 'face which approaches the edges of the cam along the substantially diametrical line at which the cam is broken away and approaches the center of rotation at an intermediatepoint. Each of these cams is adapted to cooperate with a stud or roller 38 carried by the adjacent bracket 31. A handle 39 is attached to one end of the shaft 29 soV that the 'latter may be rotated throughan appropriate angle.

It will be apparent that as the shaft 29. is rotated from the position shown in Figs. 5 and 6 to the position shown in Figures 1 and 2 the open end 371 of the cam race will pick` up the roller 38' and produce a relative movement between the brackets 31 and the` shaft 29. This at rst will simply cause the' roller 26 t0 be squeezed against the roller'14, forcing the latter downwardly at its left end until the portion 21 of .shaft 17 engages a solid portion of the frame. Subsequently, when downward movement of the roll 26 is sufhciently resisted, the brackets 31 will be raised against the action of the springs 35 which will thusbe tensionedto a greater degree. When.

the cams 37 are in their mid-positions, as shown desired to release the pressure betweenthe roll-g ers it is simply necessary to forcethe lever 39 into either of the dotted line positions shown in Figure 3. This permits the release to be effected by the same type of motion from either side. It will be apparent that in applying tension to the upper'roller it may be rocked either from the positionshown in Figure 6 or from a corresponding position on the opposite side.

In the operation of the Wringer the lower roller is preferably positively driven and the upper roller is'simply driven by friction through contact with the lower roller or with intervening clothes. To permit driving of the lower rollerit is provided with a gear 40 secured to the sleeve 15. This gear is adapted to mesh with a gear 41 secured to a horizontal drive shaft 42. When the left end of roller 14 is held in an elevated position, as 'shown in Figure 5, the teeth of gear 40 will be out of mesh with those of gear 41 but when tension is applied to the 'upper roller in the manner explained and the end of roller 14 is rocked downwardly Vthe two gears will be brought into mesh. At its opposite end the shaft 42 carries a bevel gear 43 which is constantly in mesh with bevel pinions 44 and 45 loosely mounted on a shaft 46. {Ihe lower end of this shaft is provided With pins or projections 47 to permit it to 'be readily connected with a power driving source. A clutch element 48 is splined to the shaft to permit it to slide longitudinally along the shaft and be rotated thereby. It may be placed in its lower position in which projections 49 engage recesses in the pinion 45, or it may be held in its upper position in which upper projections 49 engage recesses in the pinion 44, orl

it may be held in an intermediate, neutral position. For the purpose of shifting the clutch element to determine the direction of rotation of the rollers it may be provided with a groove around its entire periphery adapted to receive a pin 50 mounted yeccentrically with relation to a an opening 53 into a chute or channel member 54 which may be secured to the underside of the frame l0 and extend downwardly at a small angle toward both sides of the wringer. A deector beneath the opening 53 may serve 'to direct the water to one side or the other. This deflector may suitably be pivoted as shown and may be connected by a shaft 56 with a shaft 57 mounted in an opening through theshaft 42. The inner end of the shaft 57 may carry an armV having a projection adapted to ride in the groove in the pelriphery `of the element 48. In this way the deector will be adjusted in response to the shifting of the clutch to determine the direction of rota- A tion of the rollers.

' the wringer frame in any position to which it may be Vswung about the vertical axis 59. For this purpose a plunger 60 urged downwardly by va. spring 61 within a socket in the gear housing may cooperate in well known manner with recesses or openings in the top of the supporting structure.,

A bell crank lever 62 (Figure 5) carrying a pin 63 may be rocked to lift the plunger and disengage it from a recess, thus permitting the entire Wringer frame to be swung laterally. A cover member64 may be placed over the upper roller, having a telescopic t with the upright portions 11 and 12 of the frame. This cover may be simply loosely applied or latched in any suitable way, as desired.

While an illustrative form of the invention has been disclosed in considerable detail it will be understood that various changes may be made in the form, construction and arrangement of the several parts without departingl from the general spirit and scope of the invention as defined by the claims.
